濕式電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣體中的塵、酸霧、水滴、氣溶膠、臭味、PM2.5等有害物質，是治理大氣粉塵污染的理想設備。

濕式電除塵器通常簡稱WESP，與干式電除塵器的除塵基本原理相同，要經歷荷電、收集和清灰三個階段。

濕式電(dian)除塵(chen)器主要有(you)兩種結構(gou)形式，一種是(shi)使用(yong)(yong)耐(nai)腐(fu)蝕導(dao)電(dian)材料(liao)(liao)（可以為導(dao)電(dian)性(xing)能優良的的非(fei)(fei)金屬材料(liao)(liao)或具有(you)耐(nai)腐(fu)蝕特(te)性(xing)的金屬材料(liao)(liao)）做(zuo)(zuo)集塵(chen)極(ji)，另一種是(shi)用(yong)(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導(dao)電(dian)水(shui)(shui)膜，利用(yong)(yong)不導(dao)電(dian)的非(fei)(fei)金屬材料(liao)(liao)做(zuo)(zuo)集塵(chen)極(ji)。

濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)和(he)與干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)收塵(chen)(chen)原理相同，都是靠高壓(ya)電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)(de)(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下到達集塵(chen)(chen)板/管。干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)主要處理含(han)(han)水很低的(de)(de)(de)(de)干氣(qi)體，濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)主要處理含(han)(han)水較(jiao)高乃至飽(bao)和(he)的(de)(de)(de)(de)濕(shi)(shi)氣(qi)體。在(zai)對集塵(chen)(chen)板/管上捕集到的(de)(de)(de)(de)粉塵(chen)(chen)清(qing)除(chu)方(fang)(fang)式(shi)(shi)(shi)上WESP與DESP有較(jiao)大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)一(yi)般采用(yong)機械振打(da)或聲波清(qing)灰(hui)等(deng)方(fang)(fang)式(shi)(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)積灰(hui)，而濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)則采用(yong)定期沖洗的(de)(de)(de)(de)方(fang)(fang)式(shi)(shi)(shi)，使粉塵(chen)(chen)隨著沖刷液(ye)的(de)(de)(de)(de)流動而清(qing)除(chu)。
